3 Claims.

This invention relates to building constructions, and has reference moreparticularly to studs or joists together with their manner ofutilization in a building construction.

In the construction of studs, joists and like building members, it isdesirable that the memher be designed to provide the maximum of rigidityand strength when subjected to a given load. It is also desirable thatthese results be obtained with the least possible weight of metal toreduce the cost of manufacture. Building members of the class describedshould provide means for direct attachment of composition buildingboards thereto.

An object of this invention therefore, is to provide low cost buildingmembers of high rigidity and strength.

Another object of the invention is to provide metallic building membershaving means for the composition building boards; also to improvebuilding members and constructions inother respects hereinafterspecifled and claimed.

Reference is to be had to the accompanying drawing forming a part ofthis specification, in

which Fig. l is a perspective view of my improved building member,

Fig. 2 is an end elevation of the building memher, and

Fig. 3 is a sectional elevation of a building structure utilizing-thebuilding members.

Referring to the drawing by numerals, the building members may be in theform of studs I I0, joists II or other desired beam or elongated truss,the distinction between the various members ordinarily being the depthof the member between outer webs l2 of spaced channels having inwardlyextending flanges l3. In order to connect the channels H) in spacedrelation, continuous bars M are bent into zi'g-zag form in such amannerthat certain bar sections iii are attached at the bend point or fold I6to flanges l3 lying on 5' the same side of channels It, while, theadjoining bar sections I! extend diagonally betweenthe vchannels ill atan inclination to the plane of said channels In, being attached at thefold line to the opposite flange l3. Due to the alternating diagonalbracing action of the bar sections H, as

clearly seen in Fig. 2,the stud or joist has unusual- 1y high strengthand rigidity in spite of the fact that the structure is-inexpensivelymade throughout of comparatively lightweight metal. At the folds l6;thebars i5 and H may be attached to 1935, Serial No. 35,420

the inside of the flanges l3 by spot welding or 4 riveting, preferablythe former. Joists M are constructed in the same manner as hereinabovedescribed except that the distance between webs i2 is greater and aheavier metal is used throughout. The bars 15 and It may be square,rectangular orround in cross-section, or may have any other desiredshape such as angles, channels, etc.

In constructing a building through the use of my improved buildingmembers, the flanges H3 at the top of the studs are cut back and web i2is bent at right angles to form a flange is which is secured by a boltor rivet 20 to the web I2 of the lower joist channel. In order todirectly attach building sheets or boards 2! to the webs H of the studsl0 and joists H, I provide a multiplicity of perforations 22 in the websi2, these perforations being arranged in a' series of spaced groups.Holes are punched through the boards 2! by pushing a sharp pointed punchthrough said boards, the point of the punch finding one of the closelyspaced holes 22. Wood or drive screws 23 are inserted in the punchedholes after the punch is withdrawn and engage in the registeringperforations to draw the board'tightly against the channel webs l2. Theboards 2| are attached to studs II] to form partitions, and to joists Iito form ceilings and floors. These boards 2| may be composition boardsor sheets of the types well known to the art, such as gypsum board,insulation boards, hard pressed boards, asbestos boards, plywood orsheet metal. The resulting building construction may be entirelyfireproof if fireproof boards are used, and the building framework islight, inexpensive and is easily erected.

I would state in conclusion that, whilethe illustrated exampleconstitutes a practical embodiment of my invention, I do not wish tolimit myself precisely to these details, since manifestly the same maybe considerably varied without departing from the spirit of theinvention as defined in the appended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:-

1. A building member comprising a pair of elongated flat strips inspaced, parallel relation, and zig-zag bar sections connecting saidstrips, alternate bar sections extending from one edge of one strip tothe diagonally opposite edge of the other strip and the remaining barsections extending between adjacent edges of said strips.

'2. A building member comprising a pair of channel strips in spaced,parallel relation, said 10 strips having inwardly turned flanges and aweb connecting said flanges, and zig-zag bar sections secured to saidflanges and connecting said channels, certain of said bar sectionsextending at an inclination to the plane of said'channels and theremaining bar sections being substantially parallel to the plane of saidchannels, the webs of said channels being provided with a series ofclosely spaced perforations for receiving board attaching screws.
